Yarrell’s Wood-star (Calothorax Yarrelli), John Gould Several undescribed species of Humming-Birds in the collection of the late Mr. Loddiges, at Hackney, having been submitted to M. Bourcier during one of his recent visits to this country, that gentleman took the opportunity of complimenting several naturalists by giving their names to some of these new species: one of the most interesting of them he called Yarrellii, in honour of William Yarrell, Esq., so well known as one of the truest friends of natural history, and so celebrated for his valuable works on British Fishes, British Birds, &c. This illustration has been restored to its original vibrancy by enhancing colors and removing unwanted marks. A monograph of the Trochilidæ, or family of humming-birds was published between 1849 and 1887 by English ornithologist John Gould. This monumental work depicts and describes all the known species of hummingbirds at the time - comprising 418 lithographic plates and information on 537 species."
